    i know there is a formula for this but i don't know what it is.

    assume that a 120 volt, 25 cycle magnetic coil is to be rewound to operate properly on 60-cycles at the same voltage. if the coil at 25-cycles has 1,000 turns, at 60-cycles the number of turns should be most nearly what?

    the answers 416, but how?

    The relationship of 60 to 25 may give you a clue.
